Introduction
The gripping and adjustments of workpieces in laser cutting processing play an important role in the process of laser machining. The quality of cutting, accuracy and efficiency of laser cutting machining are closely related to successful fixturing and adjustment of workpiece. Therefore, when using laser cutting machine, the operator should grasp the principle, method and key points of fixturing and adjustment of workpiece.
Basic principles
The basic principle of laser cutting machine for the gripping and adjustment of workpiece is to clamp the workpiece firmly, so as to ensure the accuracy and quality of cutting. So the choice and adjustment of fixture must pay more attention, not only can not damage the workpiece, but also should have a good clamping force, so that the workpiece can be fixed firmly.
Choice of Workpiece
Before the laser cutting machine machining, for different types of materials (such as metal, rubber and wood), the operator should choose different types of fixtures, otherwise it is easy to cause the material to produce serious deformation and insufficient clamping force, or the material is easy to break.
Adjustment of Workpiece
The correct adjustment of workpiece is to install the workpiece in the laser cutting machine in the correct location and draw the line of cutting in the correct path. Galvanized and stainless steel parts should be adjusted in the following ways:
1. When the opening of the fixture is slightly larger than the workpiece, the joint gap between the upper and lower surfaces of the workpiece should be avoided.
2. a small gap between the bottom of the workpiece material and the lower surface of the fixture can be used to avoid some errors caused by the elastic deformation of the workpiece during machining.
Conclusion
From the above analysis, we can clearly understand that it is of great importance to grasps the principles, methods, key points of fixture and adjustment of workpiece for laser cutting machining. In order to ensure the successful laser cutting and excellent cutting quality, attention should be paid to the choice of fixture and the adjustment of workpiece.
